NELSON NEWMAN, OF SPRINGFIELD, ILLINOIS.

HOOP-LOCK.

SPECIFICATION forming part of Letters Patent No. 34 dated April 1886- Application filed March 25, 1885.

To all whom it may concern.-

Be it known that I, NELSON NEWMAN, of Springfield, in the county of Sangamon, and in the State of Illinois, have invented certain new and useful Improvements in Hoop-Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figures 1 to 3 are perspective views of three forms of my fastening separated from hoops. Fig. 4 is a perspective view of a barrel having its hoops secured by said fastening, and Fig. 5 is a longitudinal section through one of said fastenings and the engaging portions of a hoop.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to furnish a simple, efficient, and convenient means whereby the overlapping ends of a wooden hoop may be fastened together; and to this end said invention consists in a metal loop which is adapted to receive and inelose the overlapping ends of a hoop, and is provided upon the inner face of each end ith teeth that are adapted to engage with the contiguous face of a hoop, substantially as and for the purpose herein after specified.

In the annexed drawings, A represents a metal loop, which preferably has a rectangular form in plan view and has such width between its side bars as to permit of the ready insertion of a wooden hoop, B, with which it is to be used. The end bars, a, ofthe fastening A are flat,and are arranged transversely upon lines which are near the general plane of the body of the device, and upon their inner faces each is provided with a number of teeth, a, that have a longitudinal inward rake and at their inner ends terminate in sharp points. The fastener is now used by passing the overlapping ends of a hoop, B, through its open unobstructed center and then forcing the teeth a at each end into engagement with the surface beneath, when said hoop ends will be firmly locked in place and prevented from longitudinal outward movement. To increase or diminish the available length of said hoop, it is only necessary that the teeth at one end of said fastening be disengaged, and the parts thus liberated then drawn outward or inward the required distance, after which the mengagement of said teeth will fasten the parts again in their relative positions.

Serial No. 160,110. (No model.)

The device thus constructed is easily and quickly applied, and enables the ends of a hoop to be securely fastened together without weakening any part of the same.

As shown clearly in the drawings, the engaging teeth a a are ratchet-shaped when seen in side elevation, and have their abrupt ends turned inward or toward the middle of hooplock. The inclined faces of the teeth are formed into sharp edges, so that the teeth will cut into and so positively and most strongly engage the hoop or band upon which the lock is used. As the inner and longitudinal faces of these teeth are formed into sharp longitud nal edges, the teeth at the meeting of the inclined and the abrupt faces will obviously be quite sharp and capable of biting readily 1nto the material of the hoop or band, so that the abrupt ends of the teeth will take a most firm hold.

Having thus fully set forth the nature and merits of my invention, what I claim is 1. As anarticle of manufacture, a hoop lock consisting of a loop with its opening unobstructed, adapted to receive the overlapp ng ends of a hoop or band, and provided wlth sharp ratchet-shaped teeth proj ectiug from opposite faces of the opposite ends, andhaving their abrupt ends turned toward the middle of the loop, substantially as and for the purpose described.

2. As an article of manufacture, the loop adapted to receive the overlapping ends of a hoop or band provided on each endwit-h ratchet-shaped teeth with their inclined edges made sharp, so situated that the teeth on theopposite ends of the loop engage the outer sides of the overlapping hoop or band ends, substantially as and for the purpose described.

3. As an article of manufacture, the hooplock consisting of the loop having on the opposite faces of the opposite ends of the loop ratchetshaped teeth with sharp longitudinal edges on their inclined sides and with their abrupt cnds turned in opposite dn'ect ons, substantially as and for the purpose descrlbed.

In testimony that I claim the foregoing I have hereunto set my hand this 245th day of February, 1885.

NELSON NEWMAN.
